It started out as gate-length and then when we started building 3D transistors with FinFETs and gate-all-around, where the 2-dimensional gate-length is not comparable to "flat" transistors, they had to instead estimate the effective equivalent 2D gate-length that would give the same transistor density.
So the process name is now no longer a measure of any tangible feature size but more a descriptor of transistor density that is loosely consistent with the prior convention.
yes, I see now why you just said, "marketing"
lol
still, quite interesting
I wasn't the original commenter but I suppose you could call it marketing, sure.
